11 azarah 1.24 # relink and portage patch among others
12 vapier 1.75 #
13     # Note, this eclass does not require libtool as it only applies patches to
14     # generated libtool files. We do not run the libtoolize program because that
15     # requires a regeneration of the main autotool files in order to work properly.
